Regulation of virulence factors by quorum sensing in Vibrio harveyi. [PDF]
, 2011 Vibrio harveyi is an important aquatic pathogen that produces several virulence factors. In this study, the effect of quorum sensing, bacterial cell-to-cell communication, on the production of the virulence factors caseinase, gelatinase, lipase ...

Breaking down bacterial communication: a review of quorum quenching agents
Future Journal of Pharmaceutical Sciences, 2023 Background Bacterial cells communicate via small extracellular molecules that facilitate gene expression which is dependent on cell density and this mechanism is known as Quorum Sensing (QS).

More Bang For Your Buck: Quorum-Sensing Capabilities Improve the Efficacy of Suicidal Altruism [PDF]
, 2014 Within the context of evolution, an altruistic act that benefits the receiving individual at the expense of the acting individual is a puzzling phenomenon. An extreme form of altruism can be found in colicinogenic E. coli.

iScience, 2023 The first discovered and well-characterized bacterial quorum sensing (QS) system belongs to Vibrio fischeri, which uses N-acyl homo-serine lactones (AHLs) for cell-cell signaling. AHL QS cell-cell communication is often regarded as a cell density-dependent regulatory switch.

Penghambatan Quorum Sensing Sebagai Alternatif Terapi Penyakit Infeksi Yang Disebabkan Oleh Bakteri [PDF]
, 2005 The latest discoveries in the field of microbiology have proved that bacteria communicate eachother. The process of cell to cell communication is called quorum sensing. Quorum sensing wasfirst discovered in two luminous bacteria called Vibrio harveyi and

Cheater suppression and stochastic clearance through quorum sensing.
PLoS Computational Biology, 2022 The evolutionary consequences of quorum sensing in regulating bacterial cooperation are not fully understood. In this study, we reveal unexpected effects of regulating public good production through quorum sensing on bacterial population dynamics ...

Microfluidics-based liquid chromatography/mass spectrometry multiple reaction monitoring approach for the relative quantification of Burkholderia cenocepacia secreted virulence factors [PDF]
, 2018 Rationale: Burkholderia cenocepacia is an opportunistic pathogen that is commonly isolated from patients with cystic fibrosis (CF). Quorum sensing has been suggested to play a role in the activity of type II and type VI secretion systems and the release ...

Quorum sensing as a mechanism to harness the wisdom of the crowds
Nature Communications, 2023 Bacteria release and sense small molecules called autoinducers in a process known as quorum sensing. The prevailing interpretation of quorum sensing is that by sensing autoinducer concentrations, bacteria estimate population density to regulate the ...
